What is Speedtest3.com? And how does it function?

Speedtest3.com is a shady browser extension that supposedly functions as a tool that allows users to test the speed of their internet connection. It provides users with the Download and Upload speed of their internet, as well as its Ping and Jitter. If installed, this browser extension will change the default homepage and new tab page of your browser. However, these changes are done without your permission which makes this browser extension shadier than it already is. This is why security experts tagged it as a browser hijacker and a potentially unwanted program (PUP).

Aside from online surveys, some ads can also redirect you to dubious websites that offer free software programs and so on.
